I couldn't have said it better than this researcher - and I dont even have to translate this research for you -

"Autoimmune disorders result from a breakdown of immunologic tolerance leading to an immune response against self-molecules. In most instances the events that initiate the immune response to self-molecules are unknown, but a number of studies suggest associations with environmental and genetic factors and certain types of infections.

The concordance of autoimmune diseases among identical twins is virtually always less than 50%, often in the 25-40% range. This observation, as well as epidemic clustering of some autoimmune diseases following xenobiotic exposure, reinforces the thesis that autoimmune disease is secondary to both genetic and environmental factors. In addition, because of individual genetic susceptibilities based not only on major histocompatibility complex differences but also on differences in toxin metabolism, lifestyles, and exposure rates, individuals will rea...

The information below is taken from the FDA newsletter that I receive:

"FDA is aware of concerns that antiperspirant use -- in conjunction with underarm shaving -- may be associated with increased risk of developing breast cancer. FDA continues to search scientific literature for studies examining this possible adverse drug effect. Unfortunately, there are many publications that discuss the issue but very few studies in which data have been collected and analyzed. Overall, the studies that contain data are inconclusive in determining whether antiperspirants, in any way, contribute to the development of breast cancer. FDA hopes that definitive studies exploring breast cancer incidence and antiperspirant use will be conducted in the near future."

The issue is the aluminimum found in antiperspirants. Given this fact, numerous companies in the beauty industry are shifting away from adding aluminum and other potentially harmful ingredients to their products.

Why wait for solid proof that...
